Parts for Goldstar MV1502B: Latch Board Parts

The Microwave Door Switch is an OEM replacement part for LG countertop microwaves. It monitors the door position electrically to prevent unsafe oven operation if ajar. 

Symptoms of a bad door switch include:

• Inability to start or pause a cooking cycle unless securely latched  
• Error messages about the door being open
• Inconsistent detection of open/closed door positions
• Unreliable contact functioning after extended use

Causes involve normal wear of electrical contacts and internals through many open/close uses. Exposure to moisture intrusion from spills may potentially damage sensitive switch circuitry over time as well.

This genuine LG replacement switch is also compatible with Sears/Kenmore microwaves.

The Interlock Door Switch is an OEM part for LG microwaves. It is a safety component located on the door of the microwave designed to prevent the microwave from operating unless the door is securely closed. The interlock door switch works with the microwave's electronic control board to sense when the door is open or closed and allow or disallow operation accordingly.

Causes of a bad interlock door switch can include normal wear and tear from repeated opening and closing of the microwave door over time.

Symptoms of a bad interlock door switch include:

• The microwave runs or heats with the door open
• Error codes or diagnostic messages related to door sensors on the control board
• The microwave fails to operate even when the door is securely closed

This OEM LG part is also compatible with some Sears/Kenmore microwaves.
